DAMPER AND DAMPER-CLIP CONSTRUCTION.

Application filed October 16, 1922. Serial No. 594,835.

To all whom it may concern:

Be it known that I, THOMAS OLINGER, a citizen of the United States ofAmerica, residing at Holland, in the county of Ottawa and State ofMichigan, have invented certain new and useful Improvements in Dampersand Damper-Clip Constructions; and I do hereby declare the following tobe a full, clear, and exact description of the invention,

such as will enable others skilled in the art to which it appertains tomake and use the same. v I I This invention relates to a damperconstruction, and more particularly to'a novel clip to be used inconnection with the damper whereby a thin sheet metal disk may be usedfor the body portion of the damper, the clip being adapted for permanentconnec tion thereto at one side for use in detachably connecting theusual and regular operating handle,'said handle inthe present inventionhaving also features of novelty and an embodiment wherein its cost ofproduction is reduced to the lowest amount. Understand- 2 ing of theinvention and the novel constructions embodying the same will be hadfrom the following description, in connection with the accompanyingdrawing, in which,

Fig. 1 is a vertical cross section through 3 a furnace pipe equippedwith the damper construction of my invention, which is shown inelevation.

I Fig. 2 is a fragmentary section through.

the damper and clip, taken on the line 22, of Fig. 1.

Fig. 3 is a perspective view of a tail piece clip adapted to be attachedat the side of the damper disk directly opposite where the handle clipis attache Fig. 4 is a perspective view of said'handle clip, partlyfolded and ready for connection to the damper disk.

Fig. '5 is an elevation of the operating handle, with the usual springmounted thereon, and

Fig. 6 is a fragmentary enlarged perspective view of the damper disk atthe side where the-handle clip is to be attached.

Like reference characters refer to'like parts in the several figures ofthe drawing.

The damper disk 1 is of thin sheet metal,

circular in outline, and formed across it at a diameter thereof with arib 2 for reinforcement. At one end .of the rib, a tail clipis secured,comprising a piece of sheet metal 3 formed with a rib or embossing 4which is extended beyond the edge of the metal 3 and pointed to make aprong or tail 5 adapted to pass through an. opening in the side of thefurnace pipe in which the damper is installed. At each side of the-tail5, the clip is provided with reversely turned extensions 6 which areadapt: ed to come against the side of the disk 1 op posite to thatagainst which the part 3 bears, said extensions terminating in inwardlyturned lips 6 to pass through slots 7 in the. member 3 and'throughsimilar slots in'the disk 1, being then clinched over, as shown in Fig.1, permanently connecting the tail piece to the disk with the rib 4thereof seated inthe grooved side of rib 2011 the disk.

Near the opposite side of the disk, a relatively large opening 8 is cutthrough the disk in symmetry with the diameter of'the disk on which rib2 is formed. A slot 9 joins with the outer side of the opening, saidslot being cut in the highest portion of the rib 2. In addition twoslots 10, one at "each side of the rib and located perpendicular to theslot 9 are cut through the disk, as shown in Fig. 6.

A handle attaching clip is adapted to be secured tothe disk at suchopposite side. This clip comprises apiece of sheet metal bent to maketwo sides 11 and 12, the latter of which is cut back ateach side of itscenter to leave a projecting portion 13. Both sides 11 and 12, includingthe portion 13 are formed with ribs 14; having slots 15, similar to slot9 cut in their ends, and at the bend where sides 11 and 12' join, anelongated opening 16 is made. Lips 17 are turned from the edge of theside 12, one at each side of the portion 13 and are designed to passthrough the openings or slots 18 cut in the side 11 of the clip andthrough'like'openings or slots in the damper disk, as heretoforedescribed, at 10, being clinched against, theside 11 of the clip sothata permanent connection of the clip to the disk ismake. It willbenoted that the rib 2 "seats in the groove of the rib 14 of the side 11of the clip and that the two ribs 14 on the two sidesQll and extend inopposite directions whereby a sub stantially cylindrical opening is madefor the passage of the operating handle. "The slot 9 'and'one of theslots 15 are in conjunction,the other lot lo being directly "opposite.

eet metalclip attached atone side ofthedisk, comprising two-sides bentto, lie one at of fiat metal formed at one end with an row shaped head20 and at its other end with a widened finger engaging head 21. v Theusual coiledispring 22 is V placed around the bar 19, one-endbearingagainst thehead 21 The.,.operating handle comprises a. bar l9 and theother coming against a. disk or washer 23 which is used'tocoverthe'o'pening in a side of the furnace pipe in. which the.

damper is installed, in accordance with usual'practice. I,

its opposite side, is adapted to'be placed in alengthof furnace pipe,indicated-at, 2d, the part 5 passing through an opening in the side-ofthe pipe. The handle clip comes-adjac'ent a diametrically. opposedopening in the. pipe 24:, and the, arrow shaped head 20 ofthe operatinghandle is pa'ssedthrough sa d opening, then through the opening -16,

heretofore described, passing" between-the of the clip.v .The'he'ad 20reaches the opening handle may be turned through substantially ninetydegrees, bringing the head 20 into positionsuch thatit may be receivedinthe' notches 9 v and 15. This reception in the notches is insured bythe spring 22 which has to; bejcompressedin thc act of inserting theoperating'handle', so that when the handleis released,tthe spring drawsit back making a secure connect on o-fthe head20 with the notches 9 and1 5 in.thediskand clip.

The clip construction described is strong and durable and will. not giveway under service, and it protects the thin sheet metal damper disk fromany strain that might be" imposedby operation of the handle The damperdisk may be ofvery thingage metal, the heavier gage, metal usedn makingthe clips caring for the strains to which the damper maybe subjected inuse. The-=constructionisvery economical to produce, all parts a beingsimple stampin'gs very quickly and-easilykmade from sheet "metal: Few ofthe parts require more than one, or at the: 3 most two, operations inaxpunch; press to produce them.
